[Kroovy]

I'm 25 years old. Male. 170 pounds. I've been bed ridden for months now. I have headaches, dizziness and feeling faint. My heart rate goes up to 120 if I do anything, sometimes resting its 100. My BP bounces. It's 100 over 60 laying sown but if I just get up it's 150 over 90. My right arm is numb and leg is numb. But everytime I go to th3 er they say my hearts fast bit looks fine, cardiologist said its fine. The er just looks me over and says you're fine go home or go see a doc. Then the doctors don't know what's wrong. Rn I'm so dizzy and idk what I should do. I've been to the ER twice and they EKG me . Say my hearts fast but I'm fine and to young to have issues . Then send me home.
